FieldSENSE Designed for RF Tower Technicians’ RF safety

Safety is of the utmost importance when working around transmitting antennas. As a radio frequency (RF) worker or tower climber, you need assurance that you’re not exposed to high levels of electromagnetic radiation while working. RF workers and tower climbers globally rely on FieldSENSE personal RF monitors to help them stay safe while working.

FieldSENSE’s personal RF monitors are robust, unobtrusive, and easy-to-use making them ideal for a variety of situations. Designed with the climber in mind, they’re compact and easy to reach, yet pack a punch with their advanced technology.

This means you can keep your monitor close at hand while you’re working and quickly check your exposure level at a glance. Moreover, they clip onto your harness with a coiled tether, so you don’t have to worry about them getting in the way or dropping from a height.

The fieldSENSE60 is the next generation of personal RF monitors. It has been specifically designed to protect you from RF overexposure. It has you covered across the entire 5G frequency spectrum from 50 MHz to 60 GHz. Plus, you’re always informed of your safety status as an alarm will sound immediately as you get near to, or exceeded the permissible exposure limits.

Who is at risk of overexposure?

Isotropic

FieldSENSE personal RF monitors each have a total of six orthogonal E- and H-field probes to ensure that the combination of all sources of radiation from all angles are correctly measured and assessed in accordance with safety limits.

E- & H-fields Measured

RF Safety guidelines use the radiated power density, S in milliWatt/cm2 or Watt/m2, to assess exposure to electromagnetic fields in a given situation. This is derived from the measured E- (electric) and H- (magnetic) fields. To accurately assess a given exposure situation, both of these should be measured, especially when working very low in frequency around FM transmitters for instance. Only measuring E-field in these instances can lead to inadvertent RF overexposure.

Data Logging

The monitors have an advanced E- and H-field data logger, which records all user measurements so that they can be easily accessed over a USB connection to a PC in the office. Additionally, the data can be viewed in real-time over the USB connection with the PC application.

Voice Notes

The inbuilt logging feature allows for quick voice note taking, which can be accessed later in the office. The data is paired with the logged E- and H-fields so specific exposure conditions can easily be tagged.

Shaped Response

The exposure limits, such as the FCC (NCRP), SC6 or ICNIRP limits, are all shaped over frequency. As such, PPE must also have a shaped probe response to accurately measure in accordance with it. RF monitors without a shaped response are inaccurate and can result in an individual being overexposed.

Fall-detection & Alarm

The devices have an inbuilt fall detection system which sounds an alarm should the user accidentally fall. The alarm is easily silenced should the user still be conscious but, should they have been knocked unconscious the sounding alarm will attract the attention of colleagues. This way they are able to immediately initiate rescue actions thus reducing the potential effects of suspension trauma following a fall at height.

User Interface

FieldSENSE devices use high brightness amber LED indicators for direct sunlight visibility and have a loud buzzer to ensure the user won’t miss a thing. Additionally, it is specifically designed to be operated whilst wearing gloves.

Attachments

Devices come with an easily adjustable wrist strap to ensure comfortable attachment while working. Additionally, the fieldSENSE60 harness attachment mechanism has been completely redesigned to include a coiled lanyard system. This facilitates the smooth handling of the device during operations while still remaining visible and audible. Should the device be dropped there is no risk of it falling off the site. A tripod attachment point on the base of the device allows for setting up remote monitoring of a site, or for attaching an extension pole.

AAA batteries

The devices use readily available AAA (LR03) batteries.

“Grippy” design

The device has a custom bevelled design that fits tightly into the user’s hand with a textured soft elastomer surface and grip ridges ensuring no fumble moments.

Rugged IP64 & IK08 Enclosure

The devices have a co-moulded enclosure with a base layer of polycarbonate which is typically used in riot shields, and an outer elastomer layer made of TPU which is designed for hard wearing environments. The design provides for IP64 dust & moisture ingress rating as well as IK08 impact protection.

Zipper Case

Shipped in a heavy-duty zipper case with a custom moulded insert makes for even further protection of the device.
